Pentaerythritol tetrakis(3-mercaptopropionate) is a common thiol monomer reacted with alkenes in the thiol-ene reaction to form polymeric networks. [3] Being functionalized with four thiol groups, it can react with multifunctional alkenes to form thiol-ene networks.
3-Mercaptopropionic acid (3-MPA) is an organosulfur compound with the formula HSCH 2 CH 2 CO 2 H. It is a bifunctional molecule, containing both carboxylic acid and thiol groups. It is a colorless oil. It is derived from the addition of hydrogen sulfide to acrylic acid.
Pentaerythritol was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. [5] It may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde to give pentaerythrose (CAS: 3818-32-4), followed by a Cannizzaro reaction with a fourth equivalent of formaldehyde to give the final product plus formate ion.
It is a tetrafunctional acrylate ester used as a monomer in the manufacture of polymers. [1] As it is a polymerizable acrylate monomer, it is nearly always supplied with an added polymerisation inhibitor , such as MEHQ (monomethyl ether hydroquinone).
3-Mercaptopropionitrile is the organosulfur compound with the formula HSCH 2 CH 2 CN. [1] Containing both thiol and nitrile functional groups , it is a bifunctional compound . A colorless liquid, the compound has found some use as a masked form of thiolate.
Melting point: 141.3 °C (pure), 140–141 °C (technical) Trauzl lead block test: 523 cm 3 (other values: 500 cm 3 when sealed with sand, or 560 cm 3 when sealed with water) Critical diameter (minimal diameter of a rod that can sustain detonation propagation): 0.9 mm for PETN at 1 g/cm 3, smaller for higher densities (other value: 1.5 mm)
The suffix-oate is the IUPAC nomenclature used in organic chemistry to form names of compounds formed with ester. They are of two types: They are of two types: Formed by replacing the hydrogen atom in the –COOH by some other radical , usually an alkyl or aryl radical forming an ester .
